Brad's Seminar: In The Studio With MJ 2019 (Paris)

[Ilyes]

Hello guys, I'm sure that some of you went to the Brad Sundberg's seminar:
I would like to buy tickets for the 2019 seminar in Paris, essentially to be able to listen to demos and unreleased stuffs. Should I buy the "friday night" (55$) ticket or the complete seminar (saturday) (165$) ??
